HUB- H.

- Specification of Letters Patent.

To all whom it may concern.

Be it known that I, KNEELAND T. Smons, a citizen of the United States, and resident of Hartford in the county of Washington and State of Wisconsin, have invented certain new and useful Improvements in Hub- Caps and I do hereby declare that the following is a full, clear, and exact description thereof.

-My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out inthe claim of this specification, its object beingvto provide for simple, economical capping of hubs, especially the hubs of motorvehicle wheels, the caps being readily re-, movable but not automatically detachable.

Figure 1 of the drawings represents a side elevation of the outer shell-member of the hub of a motor vehicle wheel and a removable cap therewith in accordance with my invention, the cap being partly'in section on the plane indicatedby line 11 in Fig. 2, a groove-engaging pin of the cap being also shown in section. Fig. 2 ofthedrawings represents a transverse section of said hubm'ember and cap, the plane of the section being indicated by lineI2--2 in Fig. 1.

Referringby numerals to the drawings, 3 indicates an outer hub-member having a cylindrical extremity thereof provided with diametrically opposite and outwardly open curvilinear peripheral grooveset that alternate with similarly disposed racks 5 also provided on the periphery of said extremity of the hub. Fitting the cylindrical end of the hub-member is a cap 6 provided with inwardly extending rigid pins 7 that engage the aforesaid grooves, and hung in inner re- I cesses 8 of the cap are rack-engaging pawls 9 under pressure of springs 10 arranged in said recesses. Pivotally shackled to ends of the pawls and guided in apertures of the hub member are outwardly projecting pushpins 11, the shackle-connections serving to prevent cramping of said pawls or pins.

In practice the disengagedcap is posi- .tioned to have the pins 7 thereof register in the outer ends of the hub-grooves 4 and said cap turned on the hub until stopped by the shoulder 12 of the same.- As this operation takes place, there is slip of the spring-controlled pawls 9- over the racks 5 of the hub until the cap is full on said hub, whereupon there is an' automatic engagement of said pawls with said racks to prevent automatic detachment ofsaid cap. To remove the Patented J une 23, 1914.

cap, the push-pins 1 1 are operated, to disengage the pawls 9 from the racks 5, and

said cap turned in the proper direction to Illiage its pins 7 clear the grooves 4 of the While I have shown a preferred construction and arrangement of parts it is within the scope of my invention, as herein claimed, to omit one of the hub-grooves and racks as .well as the corresponding pin and pawl of .the cap.

I claim The combination ofa hub having a cylindrical extremity thereof provided with diametrically opposite outwardly open curvilinear peripheral grooves and similarly disposed perlpheral racks, the grooves and racks being alternate about the hub; a cap having inner pins engageable with the hubgrooves, spring-controlled pawls hung in inner recesses of the cap for engagement with the hub-racks, and a pivotal push-pin extending from each pawl through. a guideaperture in said cap.

' In testimony that I claim the foregoing I have hereunto set my handat Hartford in the county of Washington and State of Wisconsin in the presence of two witnesses.
